DETAILED DESCRIPTION

The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.

Referring to FIGS. 1-2, an electronic device includes a main body 10 configured to print files, and a paper sorting apparatus 20 connected to the main body 10. The main body 10 defines a paper outlet 11 for paper output.

The paper sorting apparatus 20 includes a chassis 30 (labeled in FIG. 7), a paper transporting module 50, and a plurality of paper trays 80 coupled to an outside of the chassis 30. The chassis 30 includes a first part 31 and a second part 33.

The first part 31 of the chassis 30 includes a bottom wall 311, a front wall 313, and two opposite sidewalls 315, 317, perpendicular to the bottom wall 311, and the front wall 313. A control module 310 is disposed at the bottom wall 311 adjacent to one of the sidewalls 317. The control module 310 includes a screw shaft 3101 and a first driving device 3173. The screw shaft 3101 extends in a direction perpendicular to the bottom wall 311. A movable member, such as a nut 316 is matched with the screw shaft 3171. A second driving device 318 is secured at the front wall 313 adjacent to the other sidewall 315. A first pivot member 319 is formed on the front wall 319.

The second part 33 includes a bottom plate 331, a rear wall 333, and two opposite side plates 335, 337, perpendicular to the bottom plate 331, and the rear wall 333. A guiding shaft 338 perpendicularly extends from the bottom plate 331 at a position corresponding to the screw shaft 3101. A slide member 339 is coupled to the guiding shaft 338. A second pivot member 336 corresponding to the first pivot member 319 is formed on the rear plate 333. When the first part 31 and the second part 33 are connected together and form the chassis 30, the chassis 30 defines a paper inlet 35 corresponding to the paper outlet 11 in the main body 10, and an opening 37 configured to accommodate the plurality of paper trays 80.

The paper transporting module 50 includes a first transporting tray 51 and a second transporting tray 53 slidably connected to the first transporting tray 51. The first transporting tray 51 has a first end 511. A first driving roller 55 is disposed at the first end 511. The driving roller 55 includes two first wheels 551 mounted at two sides of the first end 511. One of the first wheels 551 corresponds to the second driving device 318 and is configured to connect to the second driving device 318 via a first belt 312. When the second driving device 318 is in use, the driving roller 55 will be rotated. The second transporting tray 53 has a second end 531 adjacent the paper trays 80. A passive roller 57 is disposed at the second end 531. The passive roller 55 includes two second wheels 551 mounted at two sides of the second end 531. The first wheels 551 are connected to the second wheels 571 via a second belt 59. When the driving roller 55 is rotated, the passive roller 57 may be rotated by the driving roller 55.

Referring to FIGS. 3 and 4, the paper sorting apparatus further includes two belt adjusting apparatuses 60 positioned at two sides of the passive roller 57. Each belt adjusting apparatuses 60 includes a base 61 and two adjusting members 63. A pivot hole 611 and a longitudinal slot 613 are defined in the base 61. Two positioning members 615 and a blocking member 617 protrude from the base 61 and are located between the pivot holes 611 and the rectangular slot 613. Two spring members 65, such as two torsion springs, are arranged on the two positioning members 615. Each spring member 65 has a coil portion 651, a positioning end 653, and an actuating end 655.

Referring to FIG. 4, the adjusting members 63 extend through the slot 613, with one end blocked by the base 61. The coil portions of the spring members 65 surround the positioning members 615. The positioning ends 653 of the spring members 60 are secured to the blocking member 617, and the actuating ends 655 abut against the corresponding adjusting members 63, thereby providing biasing force to move the adjusting members 63 apart.

Referring to FIGS. 5 to 7, in assembly, the chassis 30 is mounted to the main body 10. The plurality of paper trays 80 are mounted to the chassis 30, with one end of each paper tray 80 accommodated in the opening 37 of the chassis 30. The paper trays 80 are aligned in a row along a direction parallel to the screw shaft 3101. The first roller 55 of the paper sorting apparatus 319 is pivotably attached to the first pivot member 319 and the second pivot member 336. The first wheel 551 is connected to the second driving device 318 via the belt 312. The first end 511 of the first paper transporting tray 51 is inserted into the paper outlet 11 of the main body 10 through the paper inlet 35 of the chassis 10. The passive roller 57 is pivotably attached to the nut 316 and the slide member 339. Two belt adjusting apparatuses 60 are pivotably connected to two ends of the passive roller 57. The second belts 59 lay over the corresponding adjusting members 63 of the belt adjusting apparatus 60 to connect the first wheels 551 to the second wheels 571. The two adjusting members 63 of each belt adjusting device 60 and one corresponding second wheel 571 is arranged in a triangle shape. The second end 531 is connected to one of the paper trays 80.

In use, the second driving device 318 drives the driving roller 55 to rotate about the first pivot member 319 and the second pivot member 336. The passive roller 57 is driven by the driving roller 55 to rotate. When paper of a print job is sent to the first paper transporting tray 51, the driving roller 55 transports the paper to the second paper transporting tray 53, and then the paper is sent to the corresponding paper tray 80 by the passive roller 57.

When a first print job is printed out and occupies one of the paper trays 80, and another print job is performed, the first driving device 3103 is run to drive the screw shaft 3101 to rotate along an axial direction. The nut 316 moves along the screw shaft 3101 and causes the second end 531 of the paper sorting apparatus 50 to move along the row of the paper trays 80 from one to another, thereby adjusting the second end 531 of the paper sorting apparatus 50 to rotate about the first end 511 and simultaneously moving along the screw shaft 317, so that the paper sorting apparatus 50 is connected to the next paper tray 80. Thus, the second print job may be transported to an empty paper tray 80. Thus, many print jobs can be sorted into different trays. During the movement, the second paper transforming tray 53 slides relative to the first paper transforming tray 51, so as to adjust a rotating radius of the paper sorting apparatus 50 when the second end 531 moves along the screw shaft.

When the second end 531 of the paper sorting apparatus 50 moves from an upper position or a lower position to a middle position, the rotating radius becomes smaller. Pressure applied on the two adjusting members 63 of each belt adjusting devices 60 is decreased. The actuating ends 655 of the spring members 65 expand out and drive the adjusting member 63 to move away from each other, to tighten the second belts 59 and cause the passive roller 57 to rotate as normal. When the second end 531 of the paper sorting apparatus 50 is moved from a middle position to an upper position or a lower position, the rotating radius becomes greater. The moving process is converse to the above. The process repeats each time a print job comes through until all trays are used then starts with the first tray 80 again. Restarting the printer can set the process back to the first tray again.
